GoogLeNet.hs: *torch* doesn't work

[Hi-Angel]

I'm getting the error:

$ runhaskell NN/Examples/GoogLeNet.hs torch --output /tmp/x.prototxt
GoogLeNet.hs: NN/CLI.hs:32:7-43: Irrefutable pattern failed for pattern Just code

Have no idea. It seems to do something with the tilde which is used in the GoogLeNet.hs, but I don't have enough experience to get anywhere further…
